Cytological Studies on Polyploids Derived from Tetraploid Fragaria Vesca and Cultivated Strawberries.
REVIOUS workers have obtained hybrid seedlings from diploid Fragaria P vesca x cultivated strawberry, but they were always sterile so that new types never became established. -4 colchicine-induced autotetraploid of F. vesca L. (DERMEN and DARROW 1938) when used in a series of crosses with the octoploid cultivated strawberry ( x F. ununassa Duch.) has given hybrids varying in fertility from comp...

متن کاملCytological Studies on Two Functional Hepatomas
The Reuber hepatoma H-35 and Morris hepatoma 5123 have been studied by electron microscopy and by cytochemical staining methods for a number of phosphatases. These studies emphasize the resemblances of the two tumors to rat liver, but they also indicate distinctive features in each of the three tissues. Secretory product accumulates within the cisternae of the Golgi apparatus that dilate to for...

متن کاملPhytochemical and Biological Studies on the Different Organs of Tanacetum parthenium L. Cultivated in Egypt
Phytochemical investigation of Tanacetum parthenium L. family Asteraceae cultivated in Egypt resulted in isolation and identification of four flavonoids. One surface flavonoid was isolated from the fresh leaves and three other flavonoids were isolated from the flower heads. Four sesquiterpene lactones were isolated from the leaves. Two sterols were isolated from the roots. A comparative study o...
